Siwon open his eyes slowly he can tell that he feel a little bit dizzy on his head and his eyes wrinkle a bit from his eyes when he was about to open it. When his eyes are in normal state vaguely Siwon saw lot of head around him so he decided to blinked his eyes and when he can clearly saw all of the head. he frowned and gasped a bit. "who are you guys ?what are you trying to do with me ?" Siwon asked them. Siwon's memory are likely a newborn baby that know nothing in his head. After that ,Siwon eyeing the whole room. A very different place from his room. The truth was he don't even know how his own room in his mind. Then he eyes trailed to all the people in that room one by one. This is not people i used to know. To be honest ,he have no specific person he knowin his head that moment. "this is not my own room. Where am i ?tell me you strangers !!" Siwon said at his own family when suddenly he feel his head ache ,with stutter he said again "answer my question can you ?one of you please. I wanna get off from here." Siwon looked all of them "you need more rest" he looked at his second brother up and down. Eunhyuk are the only person inside the room looked calm others looked so miserable and shocked. Eunhyuk hold Siwon arms tried to lying his brother on bed back. "We are in the Hospital ,aren't we ?You're my doctor ?he asked. Siwon saw a half-century women crying beside his bed ,the women as if she tried so hard to not crying. He grip her mother arms softly "Who are you madam ?why are you crying ?did you know anything about me ?" That crying women nodded and said in tears "i knew every single things of you son" Siwon release his grip on his mother because of shock. "You're my mother ?" Eunhyuk looked at everyone in the room. He answer with long answer "yes ,she is Siwon. This is your own family and you're in own house. That women beside you are your mom ,i'm your second brother ,beside me is Donghae our baby in family and this is our close cousin Heechul. That man standing near at the door's room are your dad and last one are Grandma in her own room and never care to come to see you awake now. Oh !last but not I'm your doctor too"

Mr. Choi intentionally clear his throat and shot Eunhyuk a death glared because his outspokenness about his Grandma. Siwon looked at Eunhyuk without blinked his eyes and tried to process and remember what Eunhyuk had said. Siwon tried so hard when suddenly his brain feel something like have a prick with a dozen of needle. He wrinkled his whole face and griped tightly at his bed sheet with his left hand and pinch his forehead with his right hand as a result of the ill effects and lastly whining and screaming become one. "Eeerrrggghhh ...ooouchhh !! Arrghh .." he let out his voice hardly signaling that his in very pain. Everyone in his room are very shocked and all of them come more near to him and tried to calm him while Eunhyuk put some liquid in his injection needle and went to his brother. Siwon tried to said something to Eunhyuk but when he feel the injection needle at his inside body went through his right arm muscles and were pulled out slowly his scenery in his eyes become fuzzy and he he butterfy flies in his head he forget what question he want to asked just now and suddenly all become black colour. "He really lost his memory ,am I right ?" Mrs Choi spoke hopelessly. 

the atmosphere at Korea University public cafe are very calm and full of silent. we can see Eunhyuk ,Heechul and Donghae seat by the wall on one of the modern and relaxing coffee table from outside the cafe. their face expression looked so concentrated and serious. Not with Eunhyuk or Donghae's assignment but with their family heir matter. Usually Eunhyuk and Donghae ate at their university canteen but today they changed to their university public cafe because they had Heechul with them. "Oh ! Kim So Eun !" Donghae finally break the ice in the cafe Heechul smirked and pointed at Siwon and So Eun picture that  they found in Siwon wallet "still got time to think about your girlfriend huh ?we asked you to think who is this your sister in-law ,had you even meet her before or-" Donghae cut Heechul "haiz ..her name is Kim So Eun.try google it" Eunhyuk quickily took his ipad that lying in the table before Donghae can reach and type the name. Then he clicked on Kim So Eun Pictures ,there are are a few photos come out all of it are the same women .Eunhyuk randomly clicked one of them to see clearly that photo. That was one of So Eun latest pictures at their country airport come back from U.S hugged his dad not far from them got one man aged at their peers standing with wide smile "Is that Ryeowook ?the Actiong Ceo of Kim Auto Car Company ?"

Donghae smile while bit his lips "my college buddies can't stop talking about them this lately. They said that the Ceo Heiress had come back home and ready to take over the company and how beautiful she had been after 4 years in United State. I only had one choice which is listen even I knew they are our family bussiness enemy" "hahaha they don't talked about the 3 good looking son of Choi Shi Hwa ?how pity is that" Heechul teased "YAH !"
